Dialer-Token-Pairs Field in the /etc/uucp/Devices File

The Dialer-Token-Pairs (DTP) field contains the name of a dialer and the token to pass it. The DTP field has this syntax:

dialer token [dialer token]

The dialer portion can be the name of a modem, a port monitor, or it can be direct or uudirect for a direct-link device. You can have any number of dialer-token pairs. If the dialer portion is not present, it is taken from a related entry in the Systems file. The token portion can be supplied immediately after the dialer portion.

The last dialer-token pair might not be present, depending on the associated dialer. In most situations, the last pair contains only a dialer portion. The token portion is retrieved from the Phone field of the associated Systems file entry.

A valid entry in the dialer portion can be defined in the Dialers file or can be one of several special dialer types. These special dialer types are compiled into the software and are therefore available without having entries in the Dialers file. The following list shows the special dialer types.
